DON CARLOS TRAVIS, OF KENOSI-IA, WISCONSIN, ASSIGNOR TO THE SIMMONSMANU- FACTURING COMPANY, OF KENOSHA, WISCONSIN, A CORPORATION OFWISCONSIN.

SPRING-MATTRESS FRAME.

To all 'whom t may concern:

Be it known that I, DON Cantos TRAVIS, a citizen of the United States,residing in the city of Kenosha, county of Kenosha, and State ofVisconsin, have invented certain new and useful Improvements in Spring-Mattress Frames, of which the following is a specification.

This invention relates to improvements in spring mattress frames and hasfor its salient object to provide simple and improved means for rigidlysecuring the side rails of the .frame to the end rails without the useof bolts, screws, or other fastening devices. In constructions of thischaracter the end rails may take the form of angle irons while the siderails are generally tubular in form and lie in a plane below the wirefabric or mattress.

I am aware that heretofore attempts have been made to secure the siderails to the ends of the mattress by telescopic connection or bycastings secured to the end rails and forming sockets for the sidemembers. None of these constructions however embody the simplicity andadvantages of the present invention.

The invention consists in the matters hereinafter described and moreparticularly pointed out in the appended claims.

In the drawings Figure 1 is a top plan view of a bed frame embodying mynvention, a portion of the metallic mattress being broken away. Fig. 2is a side elevation of the same. Fig. 3 is a fragmentary perspectiveview showing more clearly the manner of securing the sides to the endrails.

Referring to the drawings 1 and 2 designate the end rails which in thepresent instance take the form of inverted angle irons and 3 and 4: thetubular side rails. The latter as shown in the drawings lie in a planebelow the metallic fabric and are bent npwardly at either end as shownat 5, 5. Each end of the side rails is flattened as shown at (i and theflattened ends extend through apertures or slots 7 formed in the outerflanges 8 of the end rails. Vhen the extremities of the side rails areinserted in the slots 7, the former are bent downwardly as shown at 9,so as to lie flat upon the upper faces of the flanges 8. The side railsare secured to the end members without the use of any extraneousfastening devices of Specification of Letters Patent.

any kind. At the same time the frame members are rigidly and permanentlyunited and in such a way as to prevent any possibility of lateral orcndwise movement of the side rails. There is little or no possibility ofthe parts working loose and the construction at the same time isobviously very simple and economical. The fabric 10 is secured to theend rails by means of flat plates 11 which may be riveted or otherwisefastened to the inner flange 12 of the angle irons 1 as shown at 13. Themanner of securing the fabric to the frame however, forms no part of thepresent invention.

The essence of the present invention consists in its simplicity andreliability in construction and no extended description of the manner inwhich it is assembled is necessary. The trame as a whole supported onthe bedstead (not shown) in the usual manner, z'. e., the outer flanges8 rest upon the end members of the metal bedstead. The invention is notlimited to the detail construction shown, except as set forth in theappended claims.

I claim as my invention:

1. The combination with a pair of angle irons lying in inverted positionand forming the end rails, of a metallic mattress secured to the innerflanges of said end rails, a pair of tubular metal side rails lying in aplane below the mattress and bent upwardly at either end, theextremities of said side rails being flattened and projecting throughshort slots in the outer flanges of the end rails and bent downwardlyagainst the faces of the angle irons to lock said rail members togetheragainst lateral, or endwise movement relative to each other.

9.. In a mattress frame, the combination with a pair of angle ironsforming end rails, of a pair of tubular side rails lying in a planebelow the end rails and bent upwardly at either end, the extremities ofsaid side rails being flattened and extending through short slots formedin said angle irons and bent downwardly against the faces of said angleirons to lock said rail members together against lateral or endwisemovement relative to each other.

3. In a mattress frame, the combination with a pair of end rails, of apair of side rails, the extremities of said side rails projectingthrough small slots formed in said end rails and then bent. inwardly tolock saidbent inwardly at their extremities toV lock rail memberstogether against lateral or endthe rails together to form the frame.
